In chandler Az. I completed an HVAC tune up on a Lennox split furnace system. I inspected the cooling functions today. I checked indoor temperatures and air flow, checked amp draw and inspected fan motors, flushed drain pan and drain line, checked refrigerant charge, capacitor and tightened electrical connections. This unit is operating properly at this time. No further action is needed. A faulty thermostat was found and replaced under warranty. A Honeywell T6.
